Method And Device For Winding A Strip Consisting Of A Plurality Of Parallel Threads Onto A Drum Rotating About An Axis Of Rotation

ABSTRACT

The invention relates to a method for winding a strip ( 17 ) consisting of a plurality of parallel threads ( 18 ) onto a rotating warping drum ( 2 ), wherein the winding position of each individual thread is determined with the aid of a thread guide ( 21 ) which is associated with a thread selection device ( 8 ) and which is allocated to said thread. The thread guides ( 21 ) are displaced in the direction of the axis of rotation ( 6 ) of the warping drum ( 2 ) from a rest position into a working position and the individual threads ( 18 ) are seized successively by an internal thread carrier ( 30 ) associated with the warping drum ( 2 ).

The invention relates to a method and a device for winding a stripconsisting of a plurality of parallel threads onto a winding bodyrotating about an axis of rotation. Methods and devices of this type areused, for example, in the textile industry in weaving preparation forwarping the warp. However, winding processes are also required in othersectors, such as, for example, in the wire industry. The presentinvention, then, is not restricted to just textile applications, and theexpression “threads” covers any elongate windable element, irrespectiveof cross-sectional shape or of material.

One requirement in modern warping methods is, for example, that the workmust be carried out at high speeds, while a change in the composition ofeach wound strip should be ensured. This requirement arises particularlyin what are known as pattern warps or short warps. However, anychangeover of the strip composition, whether in generic type or thesequence of the threads or in the wound strip width, requires a machinestandstill, thus considerably delaying the work process.

An object of the invention, therefore, is to provide a method and deviceof the type initially mentioned, by means of which rapid strip changesor different strip compositions are possible at a high production speed.This object is achieved, in terms of method, by means of a method havingthe features according to claim 1 and, in terms of device, by means of adevice having the features in claim 15.

In conventional warping machines, the threads are brought to the correctthread density and strip width even on the reed. This arrangementclearly makes any modification of the strip difficult. Thesedisadvantages can be eliminated if the winding position of eachindividual thread on the winding body is defined by means of a threadguide assigned to this thread. The thread guides therefore replace thereed, although, in contrast to the latter, they can come into anydesired positions. The thread guides can therefore preferably beadjusted in the direction of the axis of rotation out of a position ofrest into a working position. The thread guides can consequently be usedalternately and thus change, as desired, the composition of the strip tobe wound.

Particularly advantageously, a thread group consisting of a plurality ofthreads, preferably of different generic type, is led up to a threadselection device arranged in the winding region of the winding body,individual threads of these being drawn off as working threads via thethread guides and forming the strip, while the remaining threads areheld clampingly as stock threads on the thread selection device in eachcase by means of a clamping point. This procedure makes it possible tocarry out the strip change while the winding body is rotatingcontinuously, thus obviously speeding up the work process considerably.

Under these circumstances, it is advantageous if, after at least onefirst winding sequence, the working threads of the wound strip areseparated and are held clampingly on the thread selection device, andif, in at least one second winding sequence, the working threads of thestrip have a composition other than that during the first windingsequence. However, the composition of the strip may also be identical ona plurality of adjacent laps. Finally, it would also be conceivable thatthe threads of a strip are not separated after each winding sequence,but, instead, the strip is guided directly, at the end of one lap, tothe start of an adjacent lap.

A thread transfer taking place during a full rotation of the windingbody can be achieved particularly advantageously when the selectedworking threads are first tensioned by means of the thread guides into atake-up position above the winding body, in which position they arefreely tensioned, approximately parallel to the axis of rotation,between the thread guides and a clamping point in each case, and inthat, in the course of a rotation of the winding body, all the workingthreads in the take-up position are picked up successively by an innerthread driver assigned to the winding body and are thereafter separatedfrom the clamping point. After separation from the clamping points, thethread guides, together with their working threads, can be moved intothe strip winding position to the strip width. This flying transfer ofthe clamped stock threads as working threads onto the winding body cantake place at high speeds and within a single rotation of the windingbody.

After the build-up of a strip lap, once again, all the working threadscan be picked up successively by an outer thread driver corotatingsynchronously with the winding body and can thereafter be clamped onceagain by the clamping point and at the same time separated from thethread guide. In practice, therefore, a flying return of the workingthreads into the standby position at the clamping points takes placeagain.

On a cone warping machine, it is clearly necessary, for the conicalwinding of the strip on a warping table, that the thread selectiondevice is displaced in the direction of the axis of rotation or at rightangles to this. The warping drum in this case forms the winding body.

Clearly, within the framework of a warping process, for the correct feedof the warp onto the beam, it is necessary to introduce dividingelements into the composite thread structure. In conventional methods,as a rule, the insertion of dividing elements always requires a machinestandstill. In the method according to the invention, this disadvantagecan be avoided in that, at the start of a strip lap, a shed is formedwith at least some of the threads at least one location on the windingbody, while the winding body is rotating, and in that a dividing elementis introduced into the open shed. Alternatively, however, the shed mayalso be formed by means of shedding combs which are arranged on an innerring corotating synchronously with the winding body and surrounding thelatter. Such thread division may preferably serve for forming a lease.Such a lease makes further processing, for example in the weaving mill,easier at a later stage. Thus, shedding, in particular leasing, and theintroduction of the dividing element at full working speed also takeplace in a similar way to the flying take-over of the working threadsonto the winding body. In specific instances, it would be conceivable toemploy this type of shedding even in conventional methods in which notevery individual thread is deposited via an individual thread guide.

Particularly advantageous shedding arises when, to beat up the lease, atleast two shedding combs arranged on the winding body one behind theother with respect to the circumferential direction are moved out of aposition of rest approximately tangential to the outer circumferenceinto a shedding position in which the comb ends project radially awayfrom the outer circumference, and, in the course of a rotation of thewinding body, the threads are preferably deposited alternately onto combends and between the comb ends. The shedding combs can in this case bemoved relatively simply with a part rotation into their workingposition. This method, however, may, of course, also be used for sizingdivision. Leasing is not involved here, but, instead, the threads are tobe kept apart from one another. For sizing division, a plurality ofshedding combs arranged on behind the other are arranged in such a waythat a shed is formed in each case for only individual threads. Ifsizing division is additionally provided, this preferably takes placebefore leasing.

Clearly, shedding and the introduction of the dividing element takeplace before the strip winding position is assumed, the thread guidesfirst being moved to a reading in position for depositing the threadsonto the shedding combs. In this reading in position, the threads lieless closely to one another than in the later strip winding position.

Preferably, a crossing rod is first introduced into an open shed, theshedding comb which forms the respective shed thereafter being movedinto the position of rest again, and, lastly, the threads divided by thecrossing rod being stripped off onto a dividing element, preferably ontoa dividing cord or a dividing band. The dividing cord or the dividingband is therefore not actually drawn into the shed, but, instead, thethreads are transferred to the dividing cord or the dividing band.

Likewise, at the end of a strip lap, a lease for shedding can be beatenup with at least some of the threads at least one location on an outerring rotating synchronously with the winding body and surrounding thelatter, a dividing element being introduced into the open shed, andshedding preferably taking place by similar means, that is to say bymeans of shedding combs, to those at the start of the strip lap.

A plurality of strip laps having an identical or a different threadrepeat can thus be wound onto the winding body one against the other ornext to one another, the winding body rotating uninterruptedly.

In terms of the device, it is expedient if in each case a thread guideand clamping point are assigned to a thread guide module which has amechanism for adjusting the thread guide and a movable clamping/cuttingunit with a clamping point for clamping the thread and with a cuttingdevice for separating the thread. The cutting and clamping of thethreads thereby take place virtually at the same location, thus makingit possible to have the flying thread change while the winding body isrotating.

The mechanism of the thread guide module is preferably a tractionmechanism with a traction means, in particular with a toothed belt onwhich the thread guide is arranged in such a way that it can be movedover a thread guide distance approximately parallel to the axis ofrotation of the winding body. The traction mechanism can be moved veryquickly and accurately, for example, by means of a stepping motor. Othertypes of mechanism would also be conceivable, however, for example apush rod, on the end of which the thread guide is arranged.

The clamping/cutting unit can be mounted movably, approximately at rightangles to the thread guide distance, in such a way that the clampingpoint is displaceable with respect to the winding body circumferencebetween a radially outer position of rest and a radially inner threadtransfer position. This stroke movement may be performed, for example,via a pneumatic pressure medium cylinder.

As is evident from FIGS. 1 and 2, a warping machine, designated as awhole by 1, consists essentially of a warping drum 2 as a winding bodywith a cylindrical portion 3 and with a conical portion 4. The warpingdrum is mounted in a stand 5 rotatably about a winding body axis or drumaxis 6. A warping table 7 rests on a warping table guide 11 and isdisplaceable on the latter parallel to the axis of rotation 6 in thedirection of the arrow c. Arranged on the warping table 7 is a threadselection device 8 which is displaceable in relation to the warping drumand at right angles to the axis of rotation of the latter, this time inthe direction of the arrow d.

The thread selection device curves around the surface of the warpingdrum 2 over a segment of, for example, 90°. A multiplicity of threadguide modules 20, illustrated merely diagrammatically here, are arrangedclosely in succession in the circumferential direction on the threadselection device. A thread group 9 is drawn off from a bobbin creel orfrom another thread dispenser device, not illustrated in more detailhere, each individual thread being guided to one of the thread guidemodules 20. Suitable devices, such as, for example, thread brakes,ensure that the threads remain constantly tensioned.

For shedding in order to produce leases or for sizing division at thestart of a lap, an inner ring 12 is arranged on the cylindrical portion3 of the warping drum 2, carries the means for leasing or for sizingdivision and rotates together with the drum. The inner ring 12 is guidedin drum longitudinal grooves 13 and can be displaced along these, in thesame way as the warping table 7, in the direction of the arrow c.

For shedding, in particular for leasing at the end of a lap, an outerring 14 is provided which surrounds the drum casing concentrically andwhich can be driven synchronously with the drum. The outer ring ismounted in an outer-ring bearing 15 which, in turn, is supported on anouter-ring slide 16 and is displaceable linearly on the latter in thedirection of the arrow c. The outer ring 14, too, carries the meansrequired for leasing.

The components for controlling the warping machine are accommodated in acontrol cabinet 10.

FIG. 3 shows diagrammatically the whole of the mechanical functiongroups on the warping machine together with the drive motors belongingto these, to be precise, essentially, the warping drum 2, the stand 5,the warping table 7 and the thread selection device 8. Included in theseare the inner ring 12 and the outer ring 14 with the respectiveactuation means. Clearly, here, both the inner ring 12 and the outerring 14 are elements which are released from the warping drum 2, butwhich can be driven in rotation synchronously with the warping drum 2.

FIG. 4 a shows a perspective part view of a thread selection device withthread guide modules of a warping machine. The thread selection device 8has a plurality of thread guide modules, the modules 20′, 20″, 20′″ and20′^(v) being arranged successively in the circumferential direction. InFIG. 3, a shedding comb 40 can also be seen, which is assigned to aninner ring and the configuration and functioning of which are describedin detail later. A thread guide 21 can be displaced to and fro orpositioned along the drum axis in the direction of the arrow e. Themovement of the thread guide 21 may take place by means of a tractionmechanism 33. Other means for moving the thread guide 21 may, of course,also be envisaged, such as, for example, pneumatic or hydraulic systems.

An individual thread guide module 20 is described in somewhat moredetail with reference to FIGS. 4 to 6. The module has a holding plate32, to which a mechanism unit 33 and a clamping/cutting unit 22 areattached. The mechanism unit has a traction mechanism with a toothedbelt 29. The toothed belt can be driven via a thread guide drive 34which is preferably a stepping motor. Fastened to one of the twoparallel toothed belt strands is a thread guide 21 which can cover athread guide distance FS in the direction of the arrow e. In theposition of rest RS, the thread guide 21 is set back behind theclamping/cutting unit. The clamping/cutting unit 22 is arranged on alifting slide 26 which is mounted displaceably in a guide 35. The drivemeans is in this case a pneumatic pressure medium cylinder 28.

The clamping/cutting unit has a double lever arm 25 which is articulatedon the lifting slide 26 and the upper lever arm of which can beactivated via a pneumatic pressure medium cylinder 27. The actualcutting device 24 is formed on the lower lever arm by a cutting edge.Directly behind the cutting plane lies a clamping point 23 which canlikewise be activated via the double lever arm 25.

The working thread supplied or the stock thread 18/19 is introduced viaa thread guide tube 36 which issues on the side of the double lever armabove the clamping point 23 in such a way that the thread lies on thethread guide distance of the thread guide 21. The thread guide has anotch or flute which prevents the thread from slipping away.

For a clearer understanding of the following functional description ofthe thread guide module 20, the inner thread driver 30 assigned to thedrum is also illustrated in FIG. 4 b. Due to means which are notillustrated in any more detail here, this inner thread driver is capableof clampingly picking up and carrying along a thread which is tensionedin the correct position.

As long as a thread is clamped to a thread guide module in the initialposition illustrated in FIG. 5, it serves as a stock thread 19 which canbe incorporated at any time as a working thread into the warping processin order to form a strip. For this purpose, according to FIGS. 7 a and 7b, the thread guide 21 is activated so that it covers part of the threadguide distance FS and first assumes a thread take-up position FM. Thelifting slide 26 is in this case already in the lowered position alsoillustrated in FIG. 5. The thread follow-up required for reaching thethread take-up position FM is drawn off via the thread guide tube 36.The rotational movement of the drum is coordinated with the movement ofthe thread guide 21 in such a way that, immediately after the threadtake-up position FM is reached, the lower thread driver 33 carries alongthis and any other working thread of the present lap.

Immediately after the thread has been reliably picked up, the clampingpoint 23 is released, so that the working thread is drawn off by thecircumferential speed of the inner thread driver 30. This situation isillustrated in FIGS. 8 a and 8 b. Up to this time point, all the activethread guide modules on the thread selection device operatesimultaneously.

After this, according to FIGS. 9 a and 9 b, the thread guide 21 is moveda little further along the thread guide distance FS, in order to read inthe thread into a shedding comb 40 for beating up a lease. This sheddingoperation is described in more detail later. The shedding comb for alease has comb ends 42 which are forked in a U-shaped manner and inwhich an individual working thread can be deposited in each case.Threads may likewise be deposited between the individual comb ends 42.As illustrated symbolically in FIG. 9 a, each thread guide 21 a, 21 b,21 c, etc. of thread guide modules following in the circumferentialdirection is then moved, in order, exactly to an extent such that aworking thread is in each case deposited alternately on a comb end andbetween a comb end. After the beating up of the lease and after theintroduction of a dividing element in the way also described below, allthe active thread guides 21, 21 a, 21 b, 21 c etc. move their respectiveworking threads into the actual winding position of the strip 17, thewidth of which is clearly substantially smaller than the thread stripwidth reading in onto the shedding comb 40. The thread guides 21 thenmaintain their relative position with respect to one another until theend of the lap is reached, the entire thread selection device beingmoved on the warping slide.

As soon as the end of a strip lap is reached and as soon as leases arealso formed there by similar means, all the active thread guides 21 moveonce again to an outer thread take-up position FM, in which all theworking threads 18 are transferred to an outer thread driver 31 or arecarried along by the latter. This outer thread driver is assigned to anouter ring 14 which surrounds the drum concentrically and corotatessynchronously with the drum and which is illustrated merely symbolicallyin FIGS. 10 a/10 b. This “gathering” of the threads takes place in orderto prepare for the cutting operation which is illustrated in FIGS. 11a/11 b.

The lifting slide 26 is in this case moved on each thread guide module20 into the upper end position, so that the clamping point 23 can pickup the drawn-off thread. The cutting device 24 is activated virtuallysimultaneously, the working thread 18 just processed being freed fromthe thread guide 21 and at the same time being held in a position ofreadiness as a stock thread 19 at the clamping point.

As is evident from FIG. 12, the means for beating up a lease at thestart of a lap are arranged on the inner ring 12. The situationillustrated in FIG. 12 corresponds in this case approximately to thataccording to FIG. 9, threads which lie next to one another being read inalternately into shedding combs 40 a, 40 b arranged one behind theother. The inner thread driver is again indicated symbolically by 30. Bythe shedding combs being wound over alternately, a lease 50 with an openshed 51, into which a dividing element can be introduced, is clearlyformed. Sizing division may also take place in about the same way. Incontrast to leasing, for sizing division a multiplicity of sheddingcombs arranged one behind the other must be provided. Furthermore, theshedding combs are designed differently for sizing division (see, inthis respect, FIGS. 28 a and 28 b).

Further details of a shedding means are evident from FIGS. 13 and 14.The curved shedding comb 40 consisting, for example, of plastic isfastened to a rotatable comb shank 41. A crossing rod 43 is arrangeddisplaceably parallel to the comb shank. A pincer-like sleeve mounting45 which clampingly grasps a dividing cord sleeve 44 is provided at theend of the prolonged comb shank 41. The approximately cylindricaldividing cord sleeve has a dividing cord spindle 46 which is screwedcentrically into the dividing cord sleeve, so that an open annular gap55 remains. A suitable dividing cord 49 is wound on the dividing cordspindle 46 and can be drawn off via the annular gap 55. The dividingcord sleeve 44 has, on the side facing the end face of the crossing rod43, a connection element 47 to which the crossing rod 43 and thedividing cord sleeve 44 can be coupled.

The extended crossing rod 43 thus grips the dividing cord sleeve 44which is fixed in the sleeve mounting 45 and, moreover, has about thesame outside diameter as the crossing rod. The sleeve mounting 45 issubsequently opened, so that the entire circumferential region of thedividing cord sleeve 44 is exposed. This makes it possible to strip offthe divided composite thread structure from the crossing rod 43 onto thedrawn-off dividing cord 49.

This purpose is served by a thread stripper 48 which is illustrated inFIG. 15 a and which is displaceable in the direction toward the dividingcord sleeve 44. FIG. 15 a/15 b show a shedding comb 40 in the positionof readiness, that is to say with comb ends 42 projecting away radiallyoutward. The crossing rod 43 is also retracted, so that, according toFIG. 16, the shedding comb can be wound over. In this case, the upperthreads 53 in each case lie in the U-shaped comb ends 42 and the lowerthreads 52 lie between the comb ends directly on the comb shank 41. Thedistance between the lower and the upper threads forms the open shed 51.Depending on the strip width of the subsequent warping strip, the entireshedding comb or only a portion of this is wound over.

As soon as all the active working threads have been read in into theshedding comb, according to FIG. 17 the crossing rod 43 is extended andthe shedding comb 40 subsequently rotated back into its radially innerposition of rest.

This situation is illustrated in FIG. 18 b. The upper threads 53 thenrest directly on the crossing rod 43 and the lower threads 52 rest, asbefore, on the comb shank 41. The crossing rod 43 has gripped thedividing cord sleeve 44 and the end face, and the latter is freed fromthe sleeve mounting 45. Then, according to FIG. 19, the thread stripper48 can be advanced, the latter stripping off the lower and upper threads52/53 beyond the dividing cord sleeve 44 onto the dividing cord 49. Thethread stripper 48 subsequently moves back again and the shedding comb40 remains in this standby position according to FIG. 20 until it isrotated out for new shedding.

Shedding at the end of a lap takes place by similar means to those atthe lap start, that is to say likewise by means of shedding combs. Asalready mentioned initially, these shedding combs are assigned to theouter ring 14, the diameter of which is dimensioned such that it islarger than the largest possible lap diameter. Contrary to the situationat the lap start, however, the dividing element is not a dividing cord,but a flexible dividing band introduced into the open shed, the designof the shed dividing means and the method steps not being the same as onthe inside. According to FIGS. 21 a/21 b, a curved shedding comb 40 withcomb ends 42 is likewise arranged on a comb shank 41. The flexibledividing band 54 with its angled end is arranged beneath the comb shank41 and can be advanced from the inside of the drum. An upper crossingrod 56 can likewise be extended parallel to the comb shank 41. Moreover,a stripping sleeve 57 is provided which surrounds the entire crossingrod 56. In the initial position illustrated, once again, lower threads52 and upper threads 53 are read in into the shedding comb 40, that isto say the thread guides 21 (FIG. 9 a) assigned to each thread ensurethat the threads assume the correct winding-over position.

According to FIG. 22, the reading in process is concluded and thecrossing rod 56 is moved into the open shed 51. Subsequently, accordingto FIG. 23, the comb shank 41 is turned away, so that the upper threads53 lie on the crossing rod 56 and the lower threads 52 lie on the combshank 41.

In a next step according to FIG. 24, the stripping sleeve 57 isextended, the lower threads 52 falling onto the dividing band 54. Bycontrast, the upper threads 53 initially still lie on the end of thecrossing rod 56. The end of the crossing rod is in this caseapproximately in alignment with the angled end of the dividing band 54.

As soon as the stripping sleeve 57 covers the last travel distance, theupper threads 53 fall onto the finished lap, but outside the dividingband 54 (FIG. 25). Consequently, the dividing element is introduced andcan be advanced by the amount of a lap width in order to form a divisionon the next following lap. The shedding comb 40 is again rotated intothe active position for shedding, and the crossing rod 56 and strippingsleeve 57 are retracted into the initial position (FIG. 26). Of course,the method described with reference to FIGS. 21 a/21 b to 26 a/26 b mayalso be adopted at the lap start or on the inner ring.

A complete winding sequence is described below with reference to thediagrammatic illustration according to FIG. 27. The diagram shows, fromthe bottom upward, the individual winding sequences, specifically with aviewing direction at right angles to the drum. In the upper third of thefigure, the viewing direction runs tangentially to the warping drum 2with the cylindrical portion 3 and with the conical portion 4, and alsowith an already finished lap 37. The lower two thirds of theillustration show virtually a development of the drum casing in thevarious operating sequences, the angular position of the drum beingindicated on the right.

A winding process commences with the feed phase 60, in which, asdescribed above, the thread selection device 8 transfers the workingthreads 18 to the drum with the aid of the active thread guides 21A andbrings them into the correct relative position. Altogether 6 activethread guides 21A are illustrated in the diagram. In the case of twopassive thread guides 21P, the corresponding thread guide modules remainin their neutral position of readiness in which the stock threads 19rest.

In the lower winding-over phase 61, the working threads 18 are read ininto the lower shedding combs 40 with the aid of the active threadguides 21A. As described above, the divided threads are pushed onto thedividing cord and the active thread guides 21A subsequently move thethreads together to the strip width B of the warping strip 17, on theone hand, and, at the same time, to the left to the foot point 38 of theconical portion 4, on the other hand. At the end of this process, thedrum has executed a revolution of 360°.

This is then followed by the actual winding phase 62 for building thelap 37, and, depending on the thread quality, a sufficient number ofdrum revolutions N×360° to ensure that the desired lap height H isreached are required.

After the lap 37 is finished, this is followed by the upper winding-overphase 63 for reading in the threads into the upper shedding combs 40 onthe outer ring 14. For this purpose, the active thread guides 21A moveeven further to the left and at the same time apart from one anotheragain to the reading in width. For shedding and for advancing thedividing band into the open sheds, the drum again requires a fullrevolution of 360°.

The thread guides 21A subsequently move together into a row, in order totransfer the working threads 18 jointly to the outer thread driver 31,the thread guide modules cutting the working threads and, in turn,gripping them clampingly. This action is illustrated as the upper feedphase 64.

Without the drum being stopped, the next lap can then be wound in thesame way, in which other threads are possibly called up on the threadselection device 8. Clearly, in this case, the inner ring 12, the outerring 14 and also the thread selection device 8 move to the right by theamount of a strip width B.

FIGS. 28 a and 28 b illustrate shedding combs for sizing division. Withthe aid of a first shedding comb 40′ (FIG. 28 a), in each case a firstthread is deposited into a comb end 42′ arranged at the start of thecomb. Further comb ends are arranged at predetermined periodic intervalsfrom one another, in each case individual threads forming a shed. Adividing element, for example a crossing rod, can be guided through thisshed. A next second shedding comb 40″ (FIG. 28 b) following the firstshedding comb has comb ends 42″ for a second thread or second threads,the comb ends of the first shedding comb being offset with respect tothe first shedding comb by the amount of one thread location. The nextshedding combs are designed similarly, that is to say, in the case ofthe third shedding comb, the respective comb ends would be offset by theamount of one further location, etc. Consequently, in the exampleaccording to FIGS. 28 a/28 b, seven shedding combs would be necessaryfor sizing division.
